'lO WHOM IT MAY GONCERN:

Be it known Athat I, CIIAR'LES SULZMAN, of Waterford, in the county of Saratoga, and State of New York, haveinvented certain new andnseful Improvements in Bolts and Locks; and I hereby declare the following to be a full, clear, and exact description of the same, reference lbeing had to the accompanying drawings, in which- Figure 1 is a perspective view from the front of my improved bolt or lock.

Figure 2 is a like view from the .rear side, showing the general arrangement of the interior parte.v

Figure 3 i s a longitudinal vertical section through the centre ci the boltcase, bolt,V and its operative mechanism. l

M y invention has for its object to produce a bolt or lock .of simplified construction and arrangement, and one which can be picked or unlocked with ditiiculty, unl-ess byone acquainted thoroughly with its organization.

The bolt, as shown in the drawings, consistsof a case, A, Vin which Athe bolt proper, B, slides, supported in the usual aperture in the end of the case, and between two ways or guides, a a. rIhe rear end 0i' 4the bolt is bevelled or recessed, so as to admit a spring, b, carrying at its free end a locking-pin, e. The bolt is moved forward and backward by means of a key or tongued arbor, C, which is operated from the outside of the case by a crank or handle, D. Near the other end of the case, and so as to occupy a proper position in relation to the locking-pin c, is a grooved wheeler disk,lE, the shaft or axis :r of which is supported in suitable bearings in the bolt-case. In the upper face of the wheel, (which has a curved or undulating surface, as shown in figs," 2 and 3,) and near its circumference, is formed an annular groove, cl, whose bottom may be pierced with a series of holes or sockets, e. In one of these sockets a bridge or stud,f, is inserted, so that its face shall be' Hush with\that of thedisk, .and lie in the plane of its curve. This bridge can `be removed and detached, so as to be set in any one of the'sockets c, as desired.

rlhe arrangement of the wheel with relation to the bolt is such that when the bridge f is in a. line with or in the plane of motion of the bolt, and the latter is turned back, or-retracted within therese by the action of the key C, the locking-pin c will ride over the bridge, and will be received into'the concave orl depressed portion of the face of the wheel immediately surrounding the axis x. When, on the contrary, the wheel is turned by means 'of a crank, K, or other suitable device for 'operating the shaft rv, so as to carry the bridge Iout of the line of movement of the bolt, the locking-pin c, thrown down bythe action of its spring, will (when the bolt is moved back by means of the key,) ride over the bevelled part, m, between the groove and the periphery ofthe wheel, and will then drop down into the groove, where itwill be held by its spring, bearing against the shoulder n, so as to prevent the further retraction of the bolt. By this means the latter may, at pleasure, be held firmly 'and securely in lposition, either projected from or withdrawn within the case.

The device shown in the drawing is a simple arrangement, adapted for use as a door-bolt. When the wheelcranl: K is in line with the letter A, the bolt can be retracted. Ii the bridge be set in any other one 0f the holes e, the crank must, of course, be turned so as to cover the letter B, 0,'01' D, corresponding tothe position of the bridge on the wheel within., It will be seen thatvby multiplying the number of these wheels, by providing the bolt with a correspondingly-increased number oi springs and locking-pins, a lock operating on the principle of a permutation lock wil-l be produced. The combinations can be changed by shifting the bridges A from one socket e to another, and there may be as many of these sockets in each wheel as deemed expedienti/ The lock and wheel or disk can, of course, be operated by ordinary keys, orany other suitable devices, linstead of by the cranks referred to.

`Having now described my invention, and the manner in which the 'same is or may be carried into effect, what I claim, and desire to secure by Letters Patent, is A l. The combination of the sliding bolt and locking-pin, and its actuating-spring, of the grooved wheel or' disk, and bridge which it carries, arranged to operate in connection. with the bolt, substantially in the manner and for the purposes shown and set forth. y

2. In a. bolt or lock,V such as described, I cluimrproviding rile grooved wheel or disk with n bridge or stud, capable of being removed from and adjusted to any one of the sockets formed in the annular grooveof the said wheel, substantially as and. for the purposes herein shown and specified.

In testimony whereof, I have signed my Vnume to this specifieation before two subscribing witnesses.

CHARLS SULZM-AN.
